Bug description:
  [Impact]

   * possible root cause of bug 1067907 and essentially ever other client using boost::unordered
   * bug 1067907 alone has ~50 reported crashes per day

  [Test Case]

   * compile and run the attached testcase

  [Regression Potential]

   * miminal patch provided as a patch by upstream -- has been fixed in
  later boost versions

  [Other Info]

  These was the original symptoms in LibreOffice causing the bug hunt --
  it has been evaded (without fixing the root cause in boost up to now)
  by not using the broken boost method in LibreOffice with
  http://cgit.freedesktop.org/libreoffice/core/commit/?id=861e55bd889d9f5f5b37724b3615e9355e2d5c15&g=libreoffice-3-6
  :

  subsequentcheck sometimes crashes in
  xmloff.Impress.XMLContentImporter::com::sun::star::document::XImporter

  Testcode:
  http://opengrok.libreoffice.org/xref/core/qadevOOo/tests/java/ifc/document/_XImporter.java
  against service:
  http://opengrok.libreoffice.org/xref/core/qadevOOo/tests/java/mod/_xmloff/Impress/XMLContentImporter.java

  steps to reproduce:
  cd xmloff
  echo "-o xmloff.Impress.XMLContentImporter" > qa/unoapi/xmloff.sce
  echo > qa/unoapi/knownissues.xcl << EOF
  xmloff.Impress.XMLContentImporter::com::sun::star::lang::XInitialization
  xmloff.Impress.XMLContentImporter::com::sun::star::document::XFilter
  xmloff.Impress.XMLContentImporter::com::sun::star::container::XNamed
  EOF
  R=T; while test "$R" = "T"; do make subsequentcheck || R=F; done

  expected result:
  test passes without a crash

  actual result:
  crash
